Economics Quiz

Suppose the government imposes a tax in a certain market in order to internalize an externality. This type of policy is based on which of the Ten Principles of Economics?

• The cost of something is what you give up to get it

• Markets are usually a good way to organize economic activity

• People respond to incentives

• People face trade-offs

Answer explanation

The government tax aims to change behavior by creating an incentive to reduce the externality. This aligns with the principle that people respond to incentives, as the tax alters the cost-benefit analysis of their actions.

In what sense do externalities cause the "invisible hand" of the marketplace to fail?

• Markets produce too little of a good when positive or negative externalities are present.

• Markets fail to produce the maximum total benefit to society when positive or negative externalities are present.

• Externalities result in prices that are too high for many consumers to pay.

• Externalities lead to government intervention in markets, which exacerbates the problems associated with externalities.

Answer explanation

Externalities cause markets to fail in maximizing total societal benefits because they lead to misallocation of resources, resulting in either overproduction or underproduction of goods, thus not reflecting true social costs or benefits.

In what sense do externalities cause the “invisible hand” of the marketplace to fail?

• Markets produce too little of a good when positive or negative externalities are present.

• Markets fail to produce the maximum total benefit to society when positive or negative externalities are present.

• Externalities result in prices that are too high for many consumers to pay.

• 
  

  Externalities lead to government intervention in markets, which exacerbates the problems associated with externalities.

Answer explanation

Externalities disrupt the market's ability to allocate resources efficiently, leading to outcomes that do not maximize societal benefits. Thus, markets fail to produce the maximum total benefit to society when externalities are present.

If a sawmill creates too much noise for local residents, ____ .

• noise restrictions will force residents to move out of the area

• the government can raise economic well-being through noise-control regulations

• the government should avoid intervening because the market will allocate resources efficiently

• a sense of social responsibility will cause owners of the mill to reduce noise levels

Answer explanation

The correct choice highlights that government intervention through noise-control regulations can improve economic well-being, addressing the noise issue for residents while balancing industrial activity.

When a negative externality exists in a market, the cost to producers ______ .

• will be the same as the cost to society

• will differ from the cost to society, regardless of whether an externality is present

• will be less than the cost to society

  
  

• is greater than the cost to society

Answer explanation

When a negative externality exists, producers do not bear the full cost of their actions, leading to lower costs for them compared to the overall societal costs. Thus, the correct choice is that their costs will be less than the cost to society.

Emission controls on automobiles are an example of a _____ .

• corrective tax

• policy to reduce congestion on urban freeways

• command-and-control policy to increase social efficiency

• policy that reduces pollution by allocating resources through market mechanisms

Answer explanation

Emission controls on automobiles are a command-and-control policy, as they set specific regulations to limit pollution, aiming to increase social efficiency by directly controlling emissions rather than using market mechanisms.

Which of the following statements about a well-maintained yard best conveys the general nature of the externality?

• A well-maintained yard conveys a positive externality because it increases the home's market value.

• A well-maintained yard conveys a positive externality because it increases the value of adjacent properties in the neighborhood

• 
  

  A well-maintained yard cannot provide any type of externality.

• A well-maintained yard conveys a negative externality because it increases the property tax liability of the owner.

Answer explanation

A well-maintained yard enhances the aesthetic appeal and overall environment of a neighborhood, thereby increasing the value of adjacent properties. This demonstrates a positive externality, as it benefits others beyond the owner.

Which of the following is not an advantage of corrective taxes?

• They move the allocation of resources closer to the social optimum

• They subsidize the production of goods with positive externalities

• They raise revenues for the government.

• 
  

  They enhance economic efficiency.

Answer explanation

Corrective taxes aim to address negative externalities, not to subsidize positive ones. Thus, they do not subsidize the production of goods with positive externalities, making this the correct choice.

One reason that private solutions to externalities do not always work is that ______ .

• interested parties incur costs in the bargaining process

  
  

• charities are not well organized

• some people benefit from externalities

• government intervention negates the benefits of positive externalities

Answer explanation

Private solutions to externalities often fail because interested parties incur costs during the bargaining process, which can hinder effective negotiation and resolution of the externality.

The difference between social cost and private cost is a measure of the _____ .

• loss in profit to the seller as the result of a negative externality

• cost of an externality

• cost reduction when the negative externality is eliminated

• cost incurred by the government when it intervenes in the market

Answer explanation

The difference between social cost and private cost reflects the cost of an externality, which is the impact of a transaction on third parties not involved in the exchange. Thus, the correct answer is the cost of an externality.
